Five "sextremists" - as Femen calls its members - took off their tops outside Ukraine's diplomatic compound in central Paris to expose their message, then crouched down and urinated on pictures of Yanukovych.

"We are calling the entire world to recognise his [Yanukovich's] opinion as something you can pee on as that is not the opinion of the nation," Femen leader and Ukrainian native Inna Shevchenko told IBTimes UK.

In a separate protest, a topless Femen activist with the words "death to dictatorship" painted on her torso chanted anti-Yanukovich slogans outside the Kievo-Pecherskaya Lavra Cathedral in Kiev.

The raids came as hundreds of thousands people took to the streets in Ukraine to protest against a government decision to pull out of an EU trade pact, a decision seen as caving in to pressure by Russia's Vladimir Putin to scupper closer Ukrainian integration with Europe.
